Applied Range



High Quality Materlals

Transparent Cover
The front fully transparent cover design allows for direct observation of the contact status and fuse on/off status without the need to remove the cover, enabling quick identification of fuse faults and improving operational efficiency.

Enhanced insulation engineering plastic material, with high mechanical strength and reliable insulation performance. The surface is designed with anti slip structure to ensure the safety and operation feel of manual opening and closing operations.
Operating Handle

Insulating Material
The housing of the isolation switch is made of high-strength flame-retardant plastic,which has high temperature resistance, impact resistance,moisture resistance and combustion resistance, and can withstand harsh environments.
Product Details
Excellent Mechanical Strength
It can withstand physical impacts,vibrations,and mechanical stresses,ensuring that the base is not easilydeformed or damaged duringinstallation or operation.
Modular And Flexible Adaptation
A complete specification covering 1P/2P/3P multipole numbers and multiple current levels, which can be flexibly combined and adapted to different circuit requirements; Supports various installation methods such as busbar type and screw fixed type.
Multi Functional Integrated Design
A single device simultaneously achieves the triple functions of electrical isolation of isolation switches, short-circuit/overload protection of fuses, and load on/off control, replacing the traditional combination scheme of "isolation switches+fuse bases", greatly saving cabinet installation space and reducing the overall cost of distribution systems.
